Triangle SRQ undergoes a rigid transformation that results in triangle VUT. 2 right triangles with identical side lengths and an
babunello [11817]

Answer:

The accurate statements are 2 and 3.

Step-by-step explanation:

Triangle SRQ undergoes a rigid transformation resulting in triangle VUT

Thus, ΔSRQ ≅ ΔVUT

Consequently, point S maps to point V, point R corresponds with point U, and point Q corresponds with point T.

Based on this information, let's review the statements:

1) SQ corresponds to VU. False as SQ corresponds to VT

2) ∠R corresponds to ∠U. True

3) UV corresponds to RS. True

4) ∠S corresponds to ∠T.  False since ∠S corresponds to ∠V

5) QS corresponds to RS. False since QS corresponds to TV

Therefore, the true statements are 2 and 3.

2) ∠R corresponds to ∠U

3) UV corresponds to RS.

Svet_ta [12734]
Insert 50 for y and solve for x.

5x + 10 (50) = 800
5x + 500 = 800
5x = 800 - 500
5x = 300
x = 300 ÷ 5
x = 60

Construct an interval estimate for the given parameter using the given sample statistic and margin of error. For μ1-μ2, using x¯
zzz [12365]

Answer: CI = (0, 8)

Step-by-step explanation: The confidence interval for the difference in means is given as

Lower limit

= (x1 - x2) + margin of error

Upper limit

= (x1 - x2) - margin of error

Where x1 - x2 = 8 and the margin of error = 8

For the lower limit,

= 8 - 8 = 0

For the upper limit

= 8 + 8 = 16

Thus, CI = (0, 8)
